Getting Started on Windows¶
The Qt library has to be built with the same version of MSVC as Python and PySide, this can be selected when using the online installer.
Python 3.8.0 was missing some API required for PySide/Shiboken so it’s not possible to use it for a Windows build.
Building from source on Windows 10¶
Creating a virtual environment¶
venv module allows you to create a local, user-writeable copy of a python environment into
which arbitrary modules can be installed and which can be removed after use:
python -m venv testenv call testenv\Scripts\activate pip install -r requirements.txt # General dependencies, documentation, and examples.
will create and use a new virtual environment, which is indicated by the command prompt changing.
Setting up CLANG¶
If you don’t have libclang already in your system, you can download from the Qt servers,
Extract the files, and leave it on any desired path, for example,
c:, and then set these two
required environment variables:
set LLVM_INSTALL_DIR=c:\libclang set PATH=C:\libclang\bin;%PATH%
Cloning the official repository can be done by:
git clone --recursive https://code.qt.io/pyside/pyside-setup
Checking out the version that we want to build, for example, 6.0:
cd pyside-setup && git checkout 6.0
Keep in mind you need to use the same version as your Qt installation
Check your Qt installation path, to specifically use that version of qmake to build PySide.
Build can take a few minutes, so it is recommended to use more than one CPU core:
python setup.py build --qmake=c:\path\to\qmake.exe --openssl=c:\path\to\openssl\bin --build-tests --ignore-git --parallel=8
To install on the current directory, just run:
python setup.py install --qmake=c:\path\to\qmake.exe --openssl=c:\path\to\openssl\bin --build-tests --ignore-git --parallel=8
You can execute one of the examples to verify the process is properly working. Remember to properly set the environment variables for Qt and PySide:
